+      Internally the sampler always fades the volume from its current value to
+      the new volume as requested, however that volume fade by default is so fast
+      that it sounds like its value jumps directly from its old to the new value,
+      it is yet slow enough though to avoid undesired click sounds. You may also

       The volume changes set by calling this function are always applied relatively to
       the volume calculated by the synthesis model and sampler format. That means
